The Characteristics of Prostate Mucinous Adenocarcinoma Visualized by 68 Ga-PSMA, 68 Ga-FAPI, and 18 F-FDG PET/CT.

Primary prostate mucinous adenocarcinoma is an exceedingly rare entity with distinct imaging characteristics. We report the case of a 62-year-old man with biopsy-proven prostate mucinous adenocarcinoma. The patient underwent MRI and multi-tracer PET/CT. PET/CT images demonstrated the prostate lesion with moderate uptake of 68 Ga-PSMA and 68 Ga-FAPI, yet significantly high 18 F-FDG uptake. No abnormal radiotracers' uptake was observed elsewhere in the body. Multi-tracer PET/CT findings suggest that 18 F-FDG may be a more suitable radiotracer for the systemic assessment of primary prostate mucinous adenocarcinoma.
